Hybrid carrot variety purple snax

ABSTRACT

The present invention relates to plants of a carrot variety PURPLE SNAX and seeds and progeny thereof. The invention further relates to methods for producing a carrot plant by traditional breeding methods. The invention further relates to a method for producing a carrot plant containing in its genetic material one or more transgenes.

FIELD OF THE INVENTION

The present invention relates to the field of plant breeding. In particular, the invention provides for a new and distinct carrot variety designated Purple Snax (or PURPLE SNAX, or “NUN 89731” or “89731” or NUN 89731 hybrid or 89732 F1, or NUN 89731 F1.

BACKGROUND OF THE INVENTION

Carrot is a biennial plant that grows a rosette of leaves in the spring and summer, while building up the stout taproot, which stores large amounts of sugars for the plant to flower in the second year. The flowering stem grows several decimeters (e.g. 60-200 cm) tall, with an umbel of white flowers that produce a fruit called a mericarp.

Carrot (Daucus carota subsp. sativus), is a root vegetable, usually orange in colour, though purple, red, white, and yellow varieties exist. It has a crisp texture when fresh. The most commonly eaten part of a carrot is a taproot, although the greens are edible as well. It is a domesticated form of the wild carrot Daucus carota, native to Europe and southwestern Asia. The domestic carrot has been selectively bred for its greatly enlarged and more palatable, less woody-textured edible taproot. The world production of carrots and turnips for calendar year 2011 was almost 35.658 million tonnes (Food and Agriculture Organization of the United Nations (FAO)).

Vegetable breeder's aim is to combine desirable traits in a single variety. Such desirable traits may include any trait deemed beneficial by a grower and/or consumer, including greater yield, resistance to insects or disease, tolerance to environmental stress, and nutritional value.

A uniform population of a breeding line can be obtained by self-pollination and selection for type. Plants thus obtained become homozygous at almost all gene loci, i.e. a homozygous plant. Crossing two such plants of different genotypes produces a uniform population of hybrid plants that are heterozygous for many loci. On the other hand, a cross of two plants each heterozygous at a number of loci produces a population of plants that differ genetically and are not uniform. Due to this non-uniformity, performance of such plants is unpredictable.

Breeders thus prefer development of homozygous inbred plant that can be crossed to produce uniform varieties. Pedigree breeding and recurrent selection are examples of breeding methods that have been used to develop inbred plants from breeding populations. Those breeding methods combine the genetic backgrounds from two or more plants or various other broad-based sources into breeding pools from which new lines and hybrids derived therefrom are developed by selfing and selection of desired phenotypes. The new lines and hybrids are evaluated to determine which of those have commercial potential.

So far, breeding efforts have provided a number of useful carrot lines with beneficial traits, however, there remains a great need in the art for new lines with further improved traits. There is thus a need for new carrot varieties having specific combination of trait or color.

The carrot plant does, thus, not differ in a statistically significant way from PURPLE SNAX in any of the morphological and/or physiological characteristics of Table 1 when grown under the same conditions, or only differs is one, two, three, four or five of the morphological and/or physiological characteristics of Table 1, while there is no significant difference in the other characteristics.

In one embodiment a carrot plant is provided, designated PURPLE SNAX, which does not (statistically significantly) differ in any of the morphological and/or physiological characteristics of Table 1 from plants grown from seeds deposited under accession number NCIMB ______ when grown under the same environmental conditions.

In yet another aspect of the invention, a tissue culture or cell-culture of regenerable cells of a carrot plant according to the invention is provided. The tissue culture or cell-culture will preferably be capable of regenerating carrot plants capable of expressing all of the physiological and morphological characteristics of the starting plant, and of regenerating plants having substantially the same genotype as the starting plant. Examples of some of the physiological and morphological characteristics of the hybrid PURPLE SNAX include those traits set forth in Table 1 herein when grown under the environmental conditions outlined herein with reference to the data of Table 1. The regenerable cells in such tissue or cell cultures may be derived, for example, from carrot explants, such as embryos, meristems, petioles, cuttings, protoplasts, cotyledons, pollen, leaves, nodes, anthers, roots, taproots, root tips, pistils, flowers, seed and stems. Still further, the present invention provides carrot plants regenerated from a tissue culture of the invention. These plants have all the physiological and morphological characteristics of a plant according to the invention.

In another aspect, the above described carrot plants are obtainable from in vitro cell or tissue cultures. As already elsewhere in this application, in vitro cell or tissue cultures are known in the art and can be used to either vegetatively reproduce the plant from which the cells or tissues were obtained or to identify and/or select a phenotypic variant (such as an EDV), and to regenerate such a variant. The phenotypic variant may, for example, be a somaclonal variant, mutant or off-type, but is preferably genetically stable. Thus, the variant phenotype is preferably genetically stable, also in the mature plants regenerated from the cell or tissue culture. That means, the phenotypic variant does not show variation in phenotype which are transient and are not genetically stable. Once selected, such selected variants can then in turn also be reproduced true to type using in vitro cell or tissue culture or by propagation via seed.

Thus in one aspect, a carrot plant is provided which is clonally propagated (it is a vegetative reproduction) from PURPLE SNAX cells or tissue and which comprises all the distinguishing characteristics of PURPLE SNAX when grown under the same environmental conditions. In another aspect it further comprises one or more of the further distinguishing characteristics. In yet another aspect it comprises all morphological and/or physiological characteristics of PURPLE SNAX as given in Table 1. And in yet a further aspect it comprises all morphological and/or physiological characteristics of PURPLE SNAX as given in Table 1, except that it significantly differs from PURPLE SNAX in one, two, three, four, or five of the morphological and/or physiological characteristics of Table 1.

The invention also concerns methods of vegetatively propagating a plant of the invention. In certain embodiments, the method comprises the steps of: (a) collecting tissue or cells capable of being propagated from a plant of the invention; (b) cultivating said tissue or cells to obtain proliferated shoots; and (c) rooting said proliferated shoots, to obtain rooted plantlets. Steps (b) and (c) may also be reversed, i.e. first cultivating said tissue to obtain roots and then cultivating the tissue to obtain shoots, thereby obtaining rooted plantlets. The rooted plantlets may then be further grown, to obtain plants. In one embodiment, the method further comprises step (d) growing plants from said rooted plantlets.

In still yet another aspect of the invention, processes are provided for producing carrot seeds, plants and roots, which processes generally comprise crossing a first parent carrot plant with a second parent carrot plant, wherein at least one of the first or second parent carrot plants is a plant according to the invention.

One embodiment of the invention refers to a method of producing a carrot plant comprising crossing a carrot plant of variety PURPLE SNAX with a second carrot plant one or more times such as one, two, three, four, five, six or more times. This method comprises in one embodiment selecting progeny from said crossing.

These processes may be further exemplified as processes for preparing hybrid carrot seed or plants, wherein a first carrot plant is crossed with a second carrot plant of a different, distinct genotype to provide a hybrid that has, as one of its parents, a plant of PURPLE SNAX.

The present invention also provides the carrot seeds and plants produced by a process that comprises crossing a first parent carrot plant with a second parent carrot plant, wherein at least one of the first or second parent carrot plants is a plant provided herein, such as from variety PURPLE SNAX.

In another embodiment of the invention, carrot seed and plants produced by the process are first filial generation (F1) carrot seed and plants produced by crossing a plant in accordance with the invention with another, distinct plant. The present invention further contemplates plant parts of such an F1 hybrid carrot plant, and methods of use thereof. Therefore, certain exemplary embodiments of the invention provide an F1 hybrid carrot plant and seed thereof.

In another embodiment of the invention, carrot variety PURPLE SNAX is crossed to produce hybrid seed of the variety designated PURPLE SNAX. In any cross herein, either parent may be the male or female parent. In these processes, crossing will result in the production of seed. The seed production occurs regardless of whether the seed is collected or not.

In certain embodiments, the invention provides methods of introducing a desired trait into a carrot plant comprising the steps of:

-   -   (a) crossing a plant of variety PURPLE SNAX with a second carrot         plant that comprises a desired trait to produce F1 progeny,     -   (b) selecting an F1 progeny that comprises the desired trait(s),         e.g., one, two, three or more desired trait(s),     -   (c) optionally selfing the F1 progeny one or more times to         produce F2, F3, or further generation selfing progeny,     -   (d) crossing the selected F1 progeny or the selfing progeny with         a plant of variety PURPLE SNAX to produce backcross progeny, and     -   (e) selecting backcross progeny comprising the desired trait(s)         and which otherwise has all or essentially all the physiological         and morphological characteristics of carrot variety PURPLE SNAX,     -   (f) optionally, steps (d) and (e) can be repeated one or more         times, e.g., three or more times such as three, four, five, six         or seven times, in succession to produce higher backcross         progeny (e.g. selected fourth, fifth, sixth, seventh or eighth         or higher backcross progeny) that comprises the desired trait.         The invention also provides carrot plants produced by these         methods; a representative sample of seed of PURPLE SNAX having         been deposited under NCIMB/ATCC Accession Number ______.

In another aspect of the invention, a carrot plant of variety PURPLE SNAX comprising an added heritable trait is provided, e.g., an Essentially Derived Variety of PURPLE SNAX having one, two or three physiological and/or morphological characteristics which are different from those of PURPLE SNAX and which otherwise has all the physiological and morphological characteristics of PURPLE SNAX, wherein a representative sample of seed of variety PURPLE SNAX has been deposited under NCIMB/ATTC Accession Number ______. The heritable trait may comprise a genetic locus that is, for example, a dominant or recessive allele. In one embodiment of the invention, a plant of the invention is defined as comprising a single locus conversion. For example, one, two, three or more heritable traits may be introgressed at any particular locus using a different allele that confers the new trait or traits of interest. In specific embodiments of the invention, the single locus conversion confers one or more traits such as, for example, herbicide tolerance, insect resistance, disease resistance and modulation of plant metabolism and metabolite profiles. In further embodiments, the trait may be conferred by a naturally occurring gene introduced into the genome of the variety by backcrossing, a natural or induced mutation, a somaclonal variant, an off-type, or a transgene introduced through genetic transformation techniques into the plant or a progenitor of any previous generation thereof. When introduced through transformation, a genetic locus may comprise one or more genes integrated at a single chromosomal location. Thus, the invention comprises a method of producing a plant comprising an added desired trait, the method comprising introducing a transgene conferring a desired trait into a plant of carrot variety PURPLE SNAX.

In still yet another aspect, the invention provides a method of determining the genotype of a plant of the invention comprising detecting in the genome of the plant at least a first polymorphism. The method may, in certain embodiments, comprise detecting a plurality of polymorphisms in the genome of the plant. For example, a sample of nucleic acid is obtained from a plant and a polymorphism or a plurality of polymorphisms is detected in said nucleic acids. The method may further comprise storing the results of the step of detecting the plurality of polymorphisms on a computer readable medium.

In one embodiment of the invention, the invention provides a method for producing a seed of a variety derived from PURPLE SNAX comprising the steps of (a) crossing a carrot plant of variety PURPLE SNAX with a second carrot plant; and (b) allowing seed of a variety PURPLE SNAX-derived carrot plant to form. This method can further comprise steps of (c) crossing a plant grown from said variety PURPLE SNAX-derived carrot seed with itself or a second carrot plant to yield additional variety PURPLE SNAX-derived carrot seed; (d) growing said additional variety PURPLE SNAX-derived carrot seed of step (c) to yield additional variety PURPLE SNAX-derived carrot plants; and optionally (e) repeating the crossing and growing steps of (c) and (d) to generate further variety PURPLE SNAX-derived carrot plants, e.g. one or more times such as two times, three times, three or more times such as four times, five times, six times, seven times or even more times. For example, the second carrot plant is of an inbred carrot variety, or alternatively, the second carrot plant in step c) is PURPLE SNAX or the male or female parent plant of PURPLE SNAX.

In still yet another aspect, the present invention provides a method of producing a plant or a seed derived from variety PURPLE SNAX, the method comprising the steps of: (a) preparing a progeny plant derived from said variety by crossing a plant of variety PURPLE SNAX with a second plant; and (b) allowing seed of a variety PURPLE SNAX-derived carrot plant to form. In one embodiment, the second plant is a plant of an inbred line or of a wild accession of Daucus carota.

The method may additionally comprise: (c) crossing a plant grown from said variety PURPLE SNAX-derived carrot seed with itself or a second carrot plant to yield additional variety PURPLE SNAX-derived carrot seed; (d) growing said additional variety PURPLE SNAX-derived carrot seed of step (c) to yield additional variety PURPLE SNAX-derived carrot plants; and optionally (e) repeating the crossing and growing steps of (c) and (d) to generate further variety PURPLE SNAX-derived carrot plants. For example, steps (c) and (d) may be repeated one or more times such as one, two, three, four five or six, seven, eight, nine, ten, or more times to produce a further plant derived from the aforementioned starting variety. The further plant derived from variety PURPLE SNAX may be an inbred variety, and the aforementioned repeated crossing steps may be defined as comprising sufficient inbreeding to produce the inbred variety. In the method, it may be desirable to select particular plants resulting from step (c) for continued crossing according to steps (b) and (c). By selecting plants having one or more desirable traits, a plant is obtained which possesses some of the desirable traits of the starting plant as well as potentially other selected traits.

In certain embodiments, the present invention provides a method of producing a carrot root comprising: (a) obtaining a plant of the invention, wherein the plant has been cultivated to maturity, and (b) collecting a carrot from said plant.

“Harvested plant material” refers herein to plant parts (e.g. a root detached from the whole plant) which have been collected for further storage and/or further use.

“Harvested seeds” refers to seeds harvested from a line or variety, e.g. produced after self-fertilization or cross-fertilization and collected.

A plant having “(essentially) all the physiological and morphological characteristics” means a plant having essentially all or all the physiological and morphological characteristics when grown under the same environmental conditions of the plant of PURPLE SNAX from which it was derived, e.g. the progenitor plant, the parent, the recurrent parent, the plant used for tissue- or cell culture, etc. The skilled person will understand that a comparison between carrot varieties should occur when said varieties are grown under the same environmental conditions. For example, the plant may have all characteristics mentioned in Table 1 when grown under the environmental conditions outlined herein with reference to the data of Table 1. In certain embodiments, the plant having “essentially all the physiological and morphological characteristics” are plants having all the physiological and morphological characteristics of Table 1, except for certain characteristics, such as one, two or three, mentioned, e.g. the characteristic(s) derived from a converted or introduced gene or trait and/or except for the characteristics which differ in an EDV. So, the plant may have all characteristics mentioned in Table 1, except for one, two or three characteristics of Table 1, in which the plant may thus differ.

A plant having one or more or all “essential physiological and/or morphological characteristics” or one or more “distinguishing characteristics” (such as one, two, three, four or five) refers to a plant having (or retaining) one or more, or all, or retaining all except one, two or three of the distinguishing characteristics mentioned in Table 1 when grown under the same environmental conditions that distinguish PURPLE SNAX from most similar varieties PURPLE HAZE and PURPLE SUN. For example, such distinguishing characteristics being selected from (but not limited to): 1) cortex thickness (midpoint cross-section), 2) length of taproot, 3) below ground exterior color of shoulder and/or skin, 4) plant top neck diameter, 5) cross-section interior color of cortex, 6) root brix level, 7) cross-section interior color of the core, 8) plant top height (from shoulder to top of crown, 9) petiole length from crown to first pinna, or 10) blade length (without petiole).

The physiological and/or morphological characteristics mentioned above are commonly evaluated at significance levels of 1%, 5%, 8% or 10% significance level, when measured under the same environmental conditions. For example, a progeny plant of PURPLE SNAX may have one or more (or all, or all except one, two or three) of the essential physiological and/or morphological characteristics of PURPLE SNAX listed in Table 1, or one or more or all (or all except one, two or three) of the distinguishing characteristics of PURPLE SNAX listed in Table 1 and above, as determined at the 1% or 5% significance level when grown under the same environmental conditions.

Physiological and/or morphological characteristics which are “substantially equivalent” or “not significantly different” or “not significantly differ” refers to a characteristic that, when compared, does not show a statistically significant difference (e.g., p≧0.05 using ANOVA) from the mean. Vice versa, “significantly different” or “statistically significantly different” refers to a characteristic that, when compared, does show a statistically significant difference (e.g., p<0.05 using ANOVA) from the mean.

As used herein, the term “variety” or “cultivar” means a plant grouping within a single botanical taxon of the lowest known rank, which grouping, irrespective of whether the conditions for the grant of a breeder's right are fully met, can be defined by the expression of the characteristics resulting from a given genotype or combination of genotypes, distinguished from any other plant grouping by the expression of at least one of the said characteristics and considered as a unit with regard to its suitability for being propagated unchanged.

The terms “gene converted” or “conversion plant” in this context refer to carrot plants which are often developed by backcrossing wherein essentially all of the desired morphological and/or physiological characteristics of parent are recovered in addition to the one or more genes transferred into the parent via the backcrossing technique or via genetic engineering. Likewise a “Single Locus Converted (Conversion) Plant” refers to plants which are often developed by plant breeding techniques comprising or consisting of backcrossing, wherein essentially all of the desired morphological and physiological characteristics of a carrot variety are recovered in addition to the characteristics of the single locus having been transferred into the variety via, e.g., the backcrossing technique and/or by genetic transformation. Likewise, a double loci converted plant/a triple loci converted plant refers to plants having essentially all of the desired morphological and/or physiological characteristics of given variety, expect that at two or three loci, respectively, it contains the genetic material (e.g., an allele) from a different variety.

A variety is referred to as an “Essentially Derived Variety” (EDV) i.e., shall be deemed to be essentially derived from another variety, “the initial variety” when (i) it is predominantly derived from the initial variety, or from a variety that is itself predominantly derived from the initial variety, while retaining the expression of the essential characteristics that result from the genotype or combination of genotypes of the initial variety; (ii) it is clearly distinguishable from the initial variety; and (iii) except for the differences which result from the act of derivation, it conforms to the initial variety in the expression of the essential characteristics that result from the genotype or combination of genotypes of the initial variety. Thus, an EDV may be obtained for example by the selection of a natural or induced mutant, or of a somaclonal variant, or an off-type, or the selection of a variant individual from plants of the initial variety, backcrossing, or transformation by genetic engineering. Such a variant may be selected at any time, e.g. in the field or greenhouse, during breeding, during or after in vitro culture of cells or tissues, during regeneration of plants, etc. The term EDV, thus, also encompassed a “phenotypic variant” derived from PURPLE SNAX seed, plant tissue or cells. In one embodiment, an EDV is a gene converted plant.

“Plant line” is for example a breeding line which can be used to develop one or more varieties.

“Hybrid variety” or “F1 hybrid” refers to the seeds of the first generation progeny of the cross of two non-isogenic plants. For example, the female parent is pollinated with pollen of the male parent to produce hybrid (F1) seeds on the female parent.

“Progeny” as used herein refers to plants derived from a plant designated PURPLE SNAX. Progeny may be derived by regeneration of cell culture or tissue culture or parts of a plant designated PURPLE SNAX or selfing of a plant designated PURPLE SNAX or by producing seeds of a plant designated PURPLE SNAX. In further embodiments, progeny may also encompass plants derived from crossing of at least one plant designated PURPLE SNAX with another carrot plant of the same or another variety or (breeding) line, or with a wild carrot plant, backcrossing, inserting of a locus into a plant or selecting a plant comprising a mutation or selecting a variant. A progeny is, e.g., a first generation progeny, i.e. the progeny is directly derived from, obtained from, obtainable from or derivable from the parent plant by, e.g., traditional breeding methods (selfing and/or crossing) or regeneration. However, the term “progeny” generally encompasses further generations such as second, third, fourth, fifth, sixth, seventh or more generations, i.e., generations of plants which are derived from, obtained from, obtainable from or derivable from the former generation by, e.g., traditional breeding methods, regeneration or genetic transformation techniques. For example, a second generation progeny can be produced from a first generation progeny by any of the methods mentioned above. Especially progeny of PURPLE SNAX which are EDVs or which retain all (or all except 1, 2 or 3) physiological and/or morphological characteristics of PURPLE SNAX listed in Table 1, or which retain all (or all except 1, 2, or 3) of the distinguishing characteristics of PURPLE SNAX described elsewhere herein and in Table 1, are encompassed herein.

The term “traditional breeding techniques” encompasses herein crossing, selfing, selection, double haploid production, embryo rescue, protoplast fusion, marker assisted selection, mutation breeding etc. as known to the breeder (i.e. methods other than genetic modification/transformation/transgenic methods), by which, for example, a genetically heritable trait can be transferred from one carrot line or variety to another.

“Crossing” refers to the mating of two parent plants.

“Cross-pollination” refers to the fertilization by the union of two gametes from different plants.

“Backcrossing” is a traditional breeding technique used to introduce a trait into a plant line or variety. The plant containing the trait is called the donor plant and the plant into which the trait is transferred is called the recurrent parent. An initial cross is made between the donor parent and the recurrent parent to produce progeny plants. Progeny plants which have the trait are then crossed to the recurrent parent. After several generations of backcrossing and/or selfing the recurrent parent comprises the trait of the donor. The plant generated in this way may be referred to as a “single trait converted plant”.

“Selling” refers to self-pollination of a plant, i.e., the transfer of pollen from the anther to the stigma of the same plant.

“Regeneration” refers to the development of a plant from cell culture or tissue culture or vegetative propagation.

“Vegetative propagation”, “vegetative reproduction” or “clonal propagation” are used interchangeably herein and mean the method of taking part of a plant and allowing that plant part to form at least roots where plant part is, e.g., defined as or derived from (e.g. by cutting of) leaf, pollen, embryo, cotyledon, hypocotyl, cells, nodes, protoplasts, meristematic cell, root, root tip, pistil, anther, flower, shoot tip, shoot, stem, petiole, etc. When a whole plant is regenerated by vegetative propagation, it is also referred to as a vegetative propagation.

The term “locus” (loci plural) means a specific place or places or a site on a chromosome where for example a gene or genetic marker is found. “Linkage” or “genetic linkage” is the tendency of genes or molecular markers that are located proximal to each other on a chromosome to be inherited together during meiosis. Genes or molecular markers whose loci are nearer to each other are less likely to be separated onto different chromatids during chromosomal crossover, and are therefore said to be genetically linked.

“Marker” or “molecular marker” refers to a readily detectable DNA sequence or nucleotide, which may be genetically closely linked to a gene or locus. Such closely linked markers can be used in MAS (marker assisted selection) of the gene or locus.

“Marker assisted selection” or “MAS” is a process of using the presence of molecular markers, which are genetically linked to a particular locus or to a particular chromosome region, to select plants for the presence of the specific locus or region.

The term “allele(s)” means any of one or more alternative forms of a gene at a particular locus, all of which alleles relate to one trait or characteristic at a specific locus. In a diploid cell of an organism, alleles of a given gene are located at a specific location, or locus (loci plural) on a chromosome. One allele is present on each chromosome of the pair of homologous chromosomes. A diploid plant species may comprise a large number of different alleles at a particular locus. These may be identical alleles of the gene (homozygous) or two different alleles (heterozygous).

As used herein, the terms “resistance” and “tolerance” are used interchangeably to describe plants that show no symptoms or significantly reduced symptoms to a specified biotic pest, pathogen, abiotic influence or environmental condition. These terms are also used to describe plants showing some symptoms but that are still able to produce marketable product with an acceptable yield. “Tissue Culture” refers to a composition comprising isolated cells or tissues of the same or a different type or a collection of such cells organized into parts of a plant.

“Transgene” or “chimeric gene” refers to a genetic locus comprising a DNA sequence which has been introduced into the genome of a carrot plant by transformation. A plant comprising a transgene stably integrated into its genome is referred to as “transgenic plant”.

“Average” refers herein to the arithmetic mean.

The term “mean” refers to the arithmetic mean of several measurements. The skilled person understands that the appearance of a plant depends to some extent on the growing conditions of said plant. Thus, the skilled person will know typical growing conditions for carrot described herein. The mean, if not indicated otherwise within this application, refers to the arithmetic mean of measurements on at least 10 different, randomly selected plants or plant parts of a variety or line.

Seeds

Also provided are seeds of carrot variety PURPLE SNAX, i.e. seeds from which the variety can be grown.

In one embodiment, a plurality of PURPLE SNAX seeds are packaged into small and/or large containers (e.g., bags, cartons, cans, etc.). Seeds may be treated with one or more chemical compounds and/or biological control agents (e.g. to improved germination, insecticidal-, acaricidal-, nematicidal- or fungicidal-compounds or compositions, etc.) and/or seeds may be primed. Biological control agents are one or more microorganisms which protect the seed or seedling against pathogens. For example, strains of bacteria and/or fungi, such as bacteria of the species of Streptomyces, Pseudomonas, Bacillus and Enterobacter or fungi of the species Phomopsis, Ectomycorrhizae, Trichoderma, Cladosporium and Gliocladium.

Priming is a water-based process that is performed on seeds to increase uniformity of germination and emergence from the soil, and thus enhance vegetable stand establishment. Methods how to prime carrot seeds are well known in the art, see WO2008/107097, describing different priming methods, such as hydro-priming (including drum-priming), osmopriming and solid-matrix priming, which can be used. The priming process may also be combined with the chemical compounds or compositions and/or biological control agent treatment, so seeds may e.g. be hydrated in a first step, dried in a second step and treated in a third step with one or more seed treatment compounds or compositions. Priming is also sometimes referred to as seed conditioning.

Hydropriming includes those techniques in which seeds are allowed to take up water for a short period or at low temperatures, mostly at ample water supply. These techniques are sometimes also referred to as soaking or steeping. With osmopriming, the seeds are exposed to an osmotic solution (see e.g. WO2008/107097).

With solid matrix priming (SMP), seeds are mixed with water and solid carriers. Examples of solid carriers are vermiculite and diatomaceous silica products. The water is taken up by the seeds as well as absorbed on the solid particle surfaces, which in this way control the water uptake of the seeds. In addition to using particle-like carriers, SMP can be carried out using, amongst others, moist towels, gunny bags, moist sand, sterilised compost or press mud as well.

So, in one aspect seeds of PURPLE SNAX are provided wherein said seeds are primed seeds and/or chemically and/or biologically treated seeds, comprising one or more chemical compounds or compositions and/or one or more biological control agents, selected from the group consisting of: a compound that improves germination, an insecticidal compound, an acaricidal compound, a nematicidal compound, and a fungicidal compound.

Breeding with Carrot Plants of the Invention

One aspect of the current invention concerns methods for crossing a carrot variety provided herein with itself or a second carrot plant and the seeds and plants produced by such methods. These methods can be used for propagation of a variety provided herein, or can be used to produce hybrid carrot seeds and the plants grown therefrom. Such hybrid seeds can be produced by crossing two parent lines or varieties to produce the hybrid variety.

In one embodiment of the invention, the first step in “crossing” comprises planting seeds of a first and a second parent carrot plant, often in proximity so that pollination will occur for example, mediated by insect vectors. Alternatively, pollen can be transferred manually. Where the plant is self-pollinated, pollination may occur without the need for direct human intervention other than plant cultivation.

A second step may comprise cultivating or growing the seeds of the first and the second parent carrot plants into plants that bear flowers. A third step may comprise preventing self-pollination of the plants. Self-incompatibility systems or male sterility (nuclear or cytoplasmic male sterility) may be used in some hybrid crops for the same purpose. In the production of hybrid carrot varieties, cytoplasmic male sterility (CMS) is widely used (see Simon et al. 2008, infra). The CMS parent line is cross pollinated with the pollen of the male-fertile parent line. The F1 seeds, i.e. the seeds from which the hybrid carrot variety is grown, are harvested from the CMS parent line. They may then be dried and cleaned, primed, pelleted and/or treated with chemical compounds (e.g. fungicides, nematicides, insecticides, etc.), before being packaged for sale.

A fourth step for a hybrid cross may comprise cross-pollination between the first and second parent carrot plants. In certain embodiments, pollen may be transferred manually or by the use of insect vectors. Yet another step comprises harvesting the seeds from at least one of the parent carrot plants. The harvested seed can be grown to produce a carrot plant or hybrid carrot plant.

The development of new varieties using one or more starting varieties is well known in the art. In accordance with the invention, a new hybrid cross in carrots is developed by using cytoplasmic male sterility (CMS) (see, e.g. pages 337-338 in Simon et al. 2008, Chapter “Carrot” pp 327-357; in the book “Vegetables II—Handbook of Plant Breeding Volume 2, 2008, ISBN 978-0-387-74108-6).

Also in accordance with the invention, novel varieties may be created by crossing a plant of the invention followed by multiple generations of breeding according to such well known methods. New varieties may be created by crossing with any second plant. In selecting such a second plant to cross for the purpose of developing novel varieties, it may be desired to choose those plants that either themselves exhibit one or more selected desirable characteristics or that exhibit the desired characteristic(s) when in hybrid combination. Once initial crosses have been made, inbreeding and selection take place to produce new varieties. For development of a uniform variety, often five or more generations of selfing and selection are involved.

Uniform varieties of new varieties may also be developed by way of double-haploids. This technique allows the creation of true breeding varieties without the need for multiple generations of selfing and selection. In this manner, true breeding varieties can be produced in as little as one generation. Haploid cells, such as microspores, pollen, anther cultures, or ovary cultures can be used. The chromosomes of the haploid cells may then be doubled autonomously, or by chemical treatments (e.g. colchicine treatment). From the double-haploid cells, fertile homozygous plants are obtained. In accordance with the invention, any of such techniques may be used in connection with a plant of the invention and progeny thereof to achieve a homozygous variety.

Backcrossing can also be used to improve an inbred plant. Backcrossing transfers one or more heritable traits from one inbred or non-inbred source to an inbred that lacks those traits. The exact backcrossing protocol will depend on the characteristic(s) or trait(s) being altered to determine an appropriate testing protocol. When the term variety PURPLE SNAX is used in the context of the present invention, this also includes plants modified to include at least a first desired heritable trait such as one, two or three desired heritable trait(s).

This can be accomplished, for example, by first crossing a superior inbred (recurrent parent) to a donor inbred (non-recurrent parent), which carries the appropriate genetic information (e.g., an allele) at the locus or loci relevant to the trait in question. The progeny of this cross are then mated back to the recurrent parent followed by selection in the resultant progeny (first backcross generation, or BC1) for the desired trait to be transferred from the non-recurrent parent. After five or more backcross generations with selection for the desired trait, the progeny are heterozygous at loci controlling the characteristic being transferred, but are like the superior parent for most or almost all other loci. The last backcross generation would be selfed to give pure breeding progeny for the trait being transferred.

The parental carrot plant which contributes the desired characteristic or characteristics is termed the non-recurrent parent because it can be used one time in the backcross protocol and therefore need not recur. The parental carrot plant to which the locus or loci from the non-recurrent parent are transferred is known as the recurrent parent as it is used for several rounds in the backcrossing protocol.

Many single locus traits have been identified that are not regularly selected for in the development of a new inbred but that can be improved by backcrossing techniques. Single locus traits may or may not be transgenic; examples of these traits include, but are not limited to, male sterility, herbicide resistance, resistance to bacterial, fungal, or viral disease, insect resistance, restoration of male fertility, modified fatty acid or carbohydrate metabolism, and enhanced nutritional quality. These comprise genes generally inherited through the nucleus.

Direct selection or screening may be applied where the single locus (e.g. allele) acts in a dominant fashion. For example, when selecting for a dominant allele providing resistance to a bacterial disease, the progeny of the initial cross can be inoculated with bacteria prior to the backcrossing. The inoculation then eliminates those plants which do not have the resistance, and only those plants which have the resistance allele are used in the subsequent backcross. This process is then repeated for all additional backcross generations.

Although backcrossing methods are simplified when the characteristic being transferred is a dominant allele, recessive, co-dominant and quantitative alleles may also be transferred. In this instance, it may be necessary to introduce a test of the progeny to determine if the desired locus has been successfully transferred. In the case where the non-recurrent variety was not homozygous, the F1 progeny would not be equivalent. F1 plants having the desired genotype at the locus of interest could be phenotypically selected if the corresponding trait was phenotypically detectable in a heterozygous or hemizygous state. In the case where a recessive allele is to be transferred and the corresponding trait is not phenotypically detectable in the heterozygous of hemizygous state, the resultant progeny can be selfed, or crossed back to the donor to create a segregating population for selection purposes. Non-phenotypic tests may also be employed. Selected progeny from the segregating population can then be crossed to the recurrent parent to make the first backcross generation (BC1).

Molecular markers may also be used to aid in the identification of the plants containing both a desired trait and having recovered a high percentage of the recurrent parent's genetic complement. Selection of carrot plants for breeding is not necessarily dependent on the phenotype of a plant and instead can be based on genetic investigations. For example, one can utilize a suitable genetic marker which is closely genetically linked to a trait of interest. One of these markers can be used to identify the presence or absence of a trait in the offspring of a particular cross, and can be used in selection of progeny for continued breeding. This technique is commonly referred to as marker assisted selection. Any other type of genetic marker or other assay that is able to identify the relative presence or absence of a trait of interest in a plant can also be useful for breeding purposes. Procedures for marker assisted selection applicable to the breeding of carrot are well known in the art. Such methods will be of particular utility in the case of recessive traits and variable phenotypes, or where conventional assays may be more expensive, time consuming or otherwise disadvantageous. Types of genetic markers which could be used in accordance with the invention include, but are not necessarily limited to, Simple Sequence Length Polymorphisms (SSLPs), Simple Sequence Repeats (SSR), Randomly Amplified Polymorphic DNAs (RAPDs), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Arbitrary Primed Polymerase Chain Reaction (AP-PCR), Amplified Fragment Length Polymorphisms (AFLPs), and Single Nucleotide Polymorphisms (SNPs).

Carrot varieties can also be developed from more than two parents. The technique, known as modified backcrossing, uses different recurrent parents during the backcrossing. Modified backcrossing may be used to replace the original recurrent parent with a variety having certain more desirable characteristics or multiple parents may be used to obtain different desirable characteristics from each.

The variety of the present invention are particularly well suited for the development of new varieties based on the elite nature of the genetic background of the variety. In selecting a second plant to cross with PURPLE SNAX for the purpose of developing novel carrot varieties, it will typically be preferred to choose those plants that either themselves exhibit one or more selected desirable characteristics or that exhibit the desired characteristic(s) when in hybrid combination. Examples of desirable characteristics may include, but are not limited to herbicide tolerance, pathogen resistance (e.g., insect resistance, nematode resistance, resistance to bacterial, fungal, and viral disease), cytoplasmic male sterility (CMS), improved harvest characteristics, enhanced nutritional quality, increased antioxidant content, improved processing characteristics, high yield, improved characteristics related to the carrot root flavor, texture, size, shape, durability, shelf life, and yield, increased soluble solids content, uniform ripening, delayed or early ripening, seedling vigor, adaptability for soil conditions, and adaptability for climate conditions.

Plants of the Invention Derived by Genetic Engineering

Many useful traits that can be introduced by backcrossing, as well as directly into a plant, are those that are introduced by genetic transformation techniques. Genetic transformation may therefore be used to insert a selected transgene into the carrot variety of the invention or may, alternatively, be used for the preparation of varieties containing transgenes that can be subsequently transferred to the variety of interest by crossing. Methods for the transformation of plants, including carrot, are well known to those of skill in the art. Techniques which may be employed for the genetic transformation of carrot include, but are not limited to Agrobacterium-mediated transformation, microprojectile bombardment, direct DNA uptake by protoplasts and electroporation.

The most common system utilizes Agrobacterium-mediated transfer for introducing gene loci into plant cells of Daucus carota (see, e.g., Rafal Baranski, 2008). An advantage of the technique is that DNA can be introduced into whole plant tissues, thereby bypassing the need for regeneration of an intact plant from a protoplast. Modern Agrobacterium transformation vectors are capable of replication in E. coli as well as Agrobacterium, allowing for convenient manipulations. Moreover, recent technological advances in vectors for Agrobacterium-mediated gene transfer have improved the arrangement of genes and restriction sites in the vectors to facilitate the construction of vectors capable of expressing various polypeptide coding genes. The vectors described have convenient multi-linker regions flanked by a promoter and a polyadenylation site for direct expression of inserted polypeptide coding genes. Additionally, Agrobacterium containing both armed and disarmed Ti genes can be used for transformation.

Exemplary nucleic acids which may be introduced to the carrot varieties of this invention include, for example, DNA sequences or genes from another species, or even genes or sequences which originate with or are present in the same species, but are incorporated into recipient cells by genetic engineering methods rather than classical reproduction or breeding techniques. However, the term “exogenous” is also intended to refer to genes that are not normally present in the cell being transformed, or perhaps simply not present in the form, structure, etc., as found in the transforming DNA segment or gene, or genes which are normally present and that one desires to express in a manner that differs from the natural expression pattern, e.g., to over-express. Thus, the term “exogenous” gene or DNA is intended to refer to any gene or DNA segment that is introduced into a recipient cell, regardless of whether a similar gene may already be present in such a cell. The type of DNA included in the exogenous DNA can include DNA which is already present in the plant cell, DNA from another plant, DNA from a different organism, or a DNA generated externally, such as a DNA sequence containing an antisense message of a gene, or a DNA sequence encoding a synthetic or modified version of a gene.

Many hundreds if not thousands of different genes are known and could potentially be introduced into a carrot plant according to the invention. Non-limiting examples of particular genes and corresponding phenotypes one may choose to introduce into a carrot plant include one or more genes for insect tolerance, such as a Bacillus thuringiensis (B.t.) gene, fungal disease tolerance, herbicide tolerance such as genes conferring glyphosate tolerance or glufosinate tolerance, and genes for quality improvements such as yield, nutritional enhancements, environmental or stress tolerances, or any desirable changes in plant physiology, growth, development, morphology or plant product(s).

Still yet another aspect of the invention refers to the genetic complement of a carrot plant variety of the invention. The phrase “genetic complement” is used to refer to the aggregate of nucleotide sequences, the expression of which defines the phenotype of, in the present case, a carrot plant of, or a cell or tissue of that plant. A genetic complement thus represents the genetic makeup of a cell, tissue or plant, and a hybrid genetic complement represents the genetic make-up of a hybrid cell, tissue or plant. The invention thus provides carrot plant cells that have a genetic complement in accordance with the carrot plant cells disclosed herein, and plants, seeds and plants containing such cells.

Plant genetic complements may be assessed by genetic marker profiles, and by the expression of phenotypic traits that are characteristic of the expression of the genetic complement, e.g., gene expression profiles, gene product expression profiles and isozyme typing profiles. It is understood that a plant of the invention or a first generation progeny thereof could be identified by any of the many well-known techniques such as, for example, Simple Sequence Length Polymorphisms (SSLPs), Randomly Amplified Polymorphic DNAs (RAPDs), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Arbitrary Primed Polymerase Chain Reaction (AP-PCR), Amplified Fragment Length Polymorphisms (AFLPs) (see, e.g., EP 534 858), and Single Nucleotide Polymorphisms (SNPs).

In still yet another aspect, the present invention provides hybrid genetic complements, as represented by carrot plant cells, tissues, plants, and seeds, formed by the combination of a haploid genetic complement of a carrot plant of the invention with a haploid genetic complement of a second carrot plant, preferably, another, distinct carrot plant. In another aspect, the present invention provides a carrot plant regenerated from a tissue culture that comprises a hybrid genetic complement of this invention.

EXAMPLES Development of PURPLE SNAX

The variety PURPLE SNAX was developed from a male and female proprietary inbred line of Nunhems. The female and male parents were crossed to produce hybrid (F1) seeds of PURPLE SNAX. The seeds of PURPLE SNAX can be grown to produce hybrid plants and parts thereof (e.g. carrot roots). The hybrid PURPLE SNAX can be propagated by seeds or vegetatively.

The hybrid variety is uniform and genetically stable. This has been established through evaluation of horticultural characteristics. Several seed production events resulted in no observable deviation in genetic stability. Coupled with the confirmation of genetic stability of the female and male parents the Applicant concluded that PURPLE SNAX is uniform and stable.

PURPLE HAZE and PURPLE SUN are considered to be the reference varieties to PURPLE SNAX. PURPLE HAZE and PURPLE SUN are commercial varieties from Nunhems. In Table 1 a comparison between PURPLE SNAX, PURPLE HAZE and PURPLE SUN is shown based on a trial in the USA. Trial location: Tracy, Calif., USA (coordinates: 37°44′17″N 121°26′2″W). Sowing date: Apr. 11, 2011, transplanting date: May 21, 2011.

Two replications of 50 plants each, from which 15 plants or plant parts were randomly selected, were used to measure characteristics. In Table 1 the USDA descriptors of PURPLE SNAX (this application) and reference varieties (commercial variety) are listed.

In accordance with one aspect of the present invention, there is provided a plant having essentially all physiological and/or morphological characteristics of carrot variety PURPLE SNAX.

In PURPLE SNAX, the color of both the xylem core and phloem core is yellow-orange (2/3), while the surrounding cortex is purple (5).

Also the degree Brix was determined in PURPLE SNAX and in the most similar varieties Purple Haze and Purple Sun.

The method used was as follows.

Carrot roots were stored at 40° F. and brought to room-temperature (72° F.). Roots were cut open horizontally. About 1 inch of root tissue was grated off the middle section of the cut-open roots (including cortex and core). The grated root tissue was placed into a garlic press and the juice was squeezed onto a refractometer (model ATAGO PR-32 Palette).
